In order to understand light condition requirements of Pyrrosia petiolosa, and better applied to landscaping, effects of five stress treatments on morphological and physiological characteristics in P petiolosa were studied, including nature light (CK, 9 000 lx), severe strong light (40 000 lx), light strong light (24 000 lx), light weak light (4 000 lx), weak light (800 lx). Relative electrical conductivity, relative chlorophyll content, relative water content, and the photosynthetic fluorescence parameters in P petiolosa stressed by ...
